One of the features that I really miss by far on iOS 6 is the ability to search for a location on Maps and find the directions to get there, by transit. It would tell me where to walk to get to a bus stop/skytrain station and what time the bus/train will leave.

iOS Maps obviously doesnt have that really useful in the city data...
Are there any apps on the app store that replicates that functionality??

There are local translink apps, but they lack the map side of the features, requiring me to know exactly the number of the bus stop that I want to catch, where it is, and which bus route I'm after. They're not smart enough to route me from A-B.

Surely, someone has made an app, pulling Google's backend data into it? Any pointers?
